[Pharo-users] Issue decoding source file
I’m getting a walkback while attempting to look at the prior versions of certain methods.It happens on some methods, but not all. I think the the issue may be related to having characters in the method body that are represented as multi-byte sequences in UTF-8. The error is 'Illegal leading byte for utf-8 encoding’ from ZnUTF8Encoder Here are the top few stack frames: ZnUTF8Encoder>>error: ZnUTF8Encoder>>errorIllegalLeadingByte ZnUTF8Encoder>>nextCodePointFromStream: ZnUTF8Encoder(ZnCharacterEncoder)>>nextFromStream: ZnCharacterReadStream>>nextElement ZnCharacterReadStream(ZnEncodedReadStream)>>peek SourceFile>>peek ChunkReadStream(DecoratorStream)>>peek ChunkReadStream>>skipSeparators ChunkReadStream>>basicNextChunk ChunkReadStream>>next SourceFileArray>>readOnlyDo: BlockClosure>>ensure: SourceFileArray>>readOnlyDo: SourceFileArray>>changeRecordsFrom:className:isMeta:do: SourceFileArray>>changeRecordsFrom:className:isMeta: VersionBrowser>>buildChangeList VersionBrowser>>buildBrowser VersionBrowser>>browseVersionsOf: Everything looks reasonable. The underlying ZnBufferedReadStream is at position 2, and the first few bytes are 159 166 34 39 46 or, in hex: 9F A6 22 27 2E That first byte, 9F or 1001, is not valid as the first byte in a UTF-8 sequence (it’s a valid continuing byte) — which presumably is why ZnUTF8Encoder is complaining. So, why is the VersionBrowser starting to look at that particular place in the source file? VersionBrowser >> buildChangeList looks like this: buildChangeList rgMethod sourcePointer ifNil:[ ^ #() ]. ^ (SourceFiles changeRecordsFrom: rgMethod sourcePointer className: rgMethod instanceSideParentName isMeta: rgMethod isMetaSide) collectWithIndex: [ :c :i | | rg | rg := c asRingDefinition. rg annotationNamed: #versionIndex put: i ] and rgMethod sourcePointer is the value of the sourcePointer attribute in the attributes dictionary in rgMehod. What can be done to fix this? Andrew

Because it provides a ton of the mechanisms for what you ask below, works well, handles a ton of periphrenalia that I really do not want to deal with directly. The good bit is that the frontend piece (the actual PWA) can be written in any way you want provided that at the end there is some JS code handling the UI. Services can be provided as cloud functions of Google Cloud and nothing prevents them from being in Pharo. In the Firebase SDK, there is a command line tool that provides for local execution of the generated JS and one can then push that code to the server side. Integration with Google general push notification system is easy to implement as well. Costs of operation are quite low, even for pushing to large user bases. There is of course the "database" component (the actual "Firebase") that is key/value pair system, along with read/write policies (which can be quite complexand support quite a number of situations very well, provided the schema is well done) and if what one needs is a relational DB, this is not really the same thing. So, that's how I would do PWAs, they work nicely using that very stack.

[Pharo-users] [ANN] PetitParser2 for VisualWorks (Was: [vwnc] Parsing in Smalltalk)
Hi, I am happy to announce that I've just finished an initial port of (the impressive) PetitParser2 (https://github.com/kursjan/petitparser2) to VisualWorks. It is available in the Public Store. The port consists of 4 bundles: * PetitParser2 * PetitParser2-Tests * PetitParser2-Smalltalk (defunct, test support only) * PetitParser2-Validation (defunct, test support only) I'd be happy to hear your comments. Cheers, Steffen

Re: [Pharo-users] Pharo for PWAs and Web Push Notifications
Have you also looked at Willow - https://link.medium.com/Iyj4qo2BfR? It has spa ‘s in mind - although I’m not sure of the pro’s/cons vs Pharo js which also looks good too. Would be interested in what you decide.

Re: [Pharo-users] ring deprecation in pharo 7
Hi, the Ring 2 is not integrated because we do not want to have two version in the system at once and we are not ready for the old Ring removal. However, it is marked as deprecated to warn people that they probably should not base their new code on it. That is important for more intensive usage of the models. Most people want to simply have something like a method reference. In that case, you can still use the old Ring. We will add some class comments to clarify that.

Re: [Pharo-users] ring deprecation in pharo 7
Hi, Ok. So, as Ring2 is not in Pharo 7 and all Ring classes in Pharo 7 are deprecated, should we still use them, or is it desired to load Ring2 in our applications?

[Pharo-users] Pharo for PWAs and Web Push Notifications
Hi all, I'm interested in developing progressive web applications (PWA) [1] in Pharo, so I'd like to know if anyone has been involved in such kind of task before and could share his experiences. At first sight, I was thinking in trying PharoJS [2] to build abstractions in Pharo for each PWA's client-side concept like Service Workers, Cache API, IndexedDB API, appshell architecture, etc. By the other hand, one of the more appealing features of PWAs is the web push notifications capability. To be able to send push notifications from a Pharo server I will also need an implementation of the Web Push Protocol [3] and the VAPID spec [4]. Do you know any previous related work in Pharo or should I think in my own implementation? Thank you!
